Hey!
Please, have a look at Servlet Methode Invocation (SMI) at the
WebAp-Framework (http://www.webapp.de).
Current features:
* SMI allows you to build modularized servlet based applications
* Direct communication between components is provided by generic
events Uses JavaBean concept
* Objects can share resources on different hierarchical levels
(I_SMIContext, I_SMIEventSwitch and SMIEvent)
* SMI support the separation of the application's logic and
it's
display
* The use of interfaces guarantees flexibility and the possibility
to extend SMI
* SMI makes direct calls to Java-methods over HTTP possible
Regrads,
Peter Rossbach
